怎么实现java快递电子面单打印接口对接demo

本篇内容介绍了"怎么实现java快递电子面单打印接口对接demo"的有关知识，在实际案例的操作过程中，不少人都会遇到这样的困境，接下来就让小编带领大家学习一下如何处理这些情况吧！希望大家仔细阅读，能够学有所成！

直接调用快递鸟API。

首先登陆快递鸟官网进行会员注册http://www.kdniao.com/reg，

然后登录快递鸟官网后台认证自己的用户信息，记住自己的用户ID和API key，代码里调用接口时会使用到。我这里主要做个物流跟踪的功能，所以我需要调用的物流跟踪API，所以我需要先订阅这个API的服务。大家如果想调用别的接口就相应的去订阅就可以了。

然后在官网找到这里 点击下载相应语言的demo

在对应的快递鸟后台，可以进行如下的批量打印。

想把这个打印功能集成到自己内部系统，可以下载官方的demo

跑起来挺容易的，直接放入tomcat运行就可以了

不过demo需要tomcat8.5，需要修改的话找到项目的.settings文件夹下有一个

org.eclipse.wst.common.project.facet.core.xml 将tomcat8.5修改为对应的版本就可以了。

官方demo代码

   }    /**      * 获取请求主机IP地址,如果通过代理进来，则透过防火墙获取真实IP地址;      *       * @param request      * @return      * @throws IOException      */    public final static String getIpAddress(HttpServletRequest request) throws IOException {        // 获取请求主机IP地址,如果通过代理进来，则透过防火墙获取真实IP地址          String ip = request.getHeader("X-Forwarded-For");        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {                ip = request.getHeader("Proxy-Client-IP");            }            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {                ip = request.getHeader("WL-Proxy-Client-IP");            }            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {                ip = request.getHeader("HTTP_CLIENT_IP");            }            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {                ip = request.getHeader("HTTP_X_FORWARDED_FOR");            }            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {                ip = request.getRemoteAddr();            }        } else if (ip.length() > 15) {            String[] ips = ip.split(",");            for (int index = 0; index < ips.length; index++) {                String strIp = (String) ips[index];                if (!("unknown".equalsIgnoreCase(strIp))) {                    ip = strIp;                    break;                }            }        }        return ip;    }}

但是，需要注意的是，API有一个ip参数，获取这个ip快递鸟提供的方法是如下

// 获取请求主机IP地址,如果通过代理进来，则透过防火墙获取真实IP地址      public final static String getIpAddress(HttpServletRequest request) throws IOException {        String ip = request.getHeader("X-Forwarded-For");        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {                ip = request.getHeader("Proxy-Client-IP");            }            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {                ip = request.getHeader("WL-Proxy-Client-IP");            }            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {                ip = request.getHeader("HTTP_CLIENT_IP");            }            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {                ip = request.getHeader("HTTP_X_FORWARDED_FOR");            }            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {                ip = request.getRemoteAddr();            }        } else if (ip.length() > 15) {            String[] ips = ip.split(",");            for (int index = 0; index < ips.length; index++) {                String strIp = (String) ips[index];                if (!("unknown".equalsIgnoreCase(strIp))) {                    ip = strIp;                    break;                }            }        }        return ip;    }

注意这个方法是没有问题的，但是你如果直接输入快递单号OrderCode进行打印，这个时候提交总是说数据验证不通过，并不是签名问题，而是ip问题。

因为上一个方法只要是在局域网下面，即使能访问外网，也没用，获取到的ip永远都是内网ip

有一种方式可以在本地验证通过，那就是直接百度ip，只有会有自己的ip地址

OK，在后台将ip写死，就可以进行打印预览操作了。

打印需要安装lodop打印插件，安装完成之后访问 http://localhost:8000/CLodopfuncs.js 会有相应的控件js

需要对应的打印插件，必须要有设备(热敏打印机)，要不我也不至于出差了。

之后根据打印机型号，进入对应的官网下载打印驱动。之后perfect，就可以进行打印了。

官方demo给的是servlet

我使用的是SpringMVC，将代码贴出。

final String EBussinessID = "12677**";//kdniao.com EBusinessID    final String AppKey = "8e9dcb4b-f0a1-42f6-9d80-372a67f851**"; //kdniao.com AppKey    final Integer IsPreview = 1; //是否预览 0-不预览 1-预览    @RequestMapping("/getCloudPrintData.do")    @ResponseBody    public Map getCloudPrintData(HttpServletRequest request,String OrderCode,String ip) throws Exception{        System.out.println("ok:"+OrderCode+"---"+ip);        Map map = new HashMap();        List> list = new ArrayList>();        Map dataMap = new HashMap();        dataMap.put("OrderCode", OrderCode);        dataMap.put("PortName", "Xprinter XP-DT108A LABEL");        list.add(dataMap);        String jsonString = JSONArray.fromObject(dataMap).toString();                map.put("RequestData", URLEncoder.encode(jsonString, "UTF-8"));        if(StringUtils.isEmpty(ip)) {            ip = getIpAddress(request);        }        map.put("DataSign",encrpy(ip + jsonString, AppKey));        System.out.println("map:"+map);        return map;    }        @RequestMapping("/getIpAddressByJava.do")    @ResponseBody    public String getIpAddressByJava(HttpServletRequest request) throws IOException {        return getIpAddress(request);    }        private String encrpy(String content, String key) throws UnsupportedEncodingException, Exception {        String charset = "UTF-8";        return new String(Base64.encode(md5(content + key, charset).getBytes(charset)));    }        private String md5(String str, String charset) throws Exception {        MessageDigest md = MessageDigest.getInstance("MD5");        md.update(str.getBytes(charset));        byte[] result = md.digest();        StringBuffer sb = new StringBuffer(32);        for (int i = 0; i < result.length; i++) {            int val = result[i] & 0xff;            if (val <= 0xf) {                sb.append("0");            }            sb.append(Integer.toHexString(val));        }        return sb.toString().toLowerCase();    }        // 获取请求主机IP地址,如果通过代理进来，则透过防火墙获取真实IP地址      public final static String getIpAddress(HttpServletRequest request) throws IOException {        String ip = request.getHeader("X-Forwarded-For");        if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {                ip = request.getHeader("Proxy-Client-IP");            }            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {                ip = request.getHeader("WL-Proxy-Client-IP");            }            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {                ip = request.getHeader("HTTP_CLIENT_IP");            }            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {                ip = request.getHeader("HTTP_X_FORWARDED_FOR");            }            if (ip == null || ip.length() == 0 || "unknown".equalsIgnoreCase(ip)) {                ip = request.getRemoteAddr();            }        } else if (ip.length() > 15) {            String[] ips = ip.split(",");            for (int index = 0; index < ips.length; index++) {                String strIp = (String) ips[index];                if (!("unknown".equalsIgnoreCase(strIp))) {                    ip = strIp;                    break;                }            }        }        return ip;    }
